high-powered XXX is uregently needed reinforced material of fields ,such as defense-related weaponry industy,light-weight automobile and huge airplane-making industy,but druing the composite materials the perfect mechanical property is concentrate upon the axial direction of XXX.The
interfacial adhesion strength of axial direction is weak, which leads that the gamage of composite materials.This progame uses covalent bond grafting the carbon nanotubes to form multiple dimensioned enhanceosome by hydroface-electrochemical process.promissing to realizeing optimization design of "isotropism" on the surface texture of XXX, which means that the composite material function of horizontal and vertical of XXX will be strengthened simultaneously.This project studyed the mass transfer,adsorption ,reaction mechanism of carbon nanotube carboxyl anion under the ultrasonic-assisted treatment of electrochemical system and influence of XXX's mechanical property by electrochemical grafting .And it illuminates that the reaction mechanism of hydroface-electrochemistry and control mechanism of surface structure of XXX, and
it investigates preliminarily influencing mechanism of XXX surface grafted
carbon nanotube to interface between XXX of composite material and
colophony. Of this progame the innovation point is that it invents a new
preparation method of XXX/carbon nanotube duplex fibre ,which is reaction-mildness and controllable,environment-friendly and industrialization-feasible,which is significant to develop the next generation-high performance XXX and composite materials. |
